I am mentioning the points on the topic of eco-friendliness of E-Ticketing system.
There may not be any
harmful effects of e-ticketing systems directly on our ecosystem. But the
computers based on which e-ticketing works, have effects.
1. E-ticketing solution uses computer hardware.
The monitors used for display contain some harmful substances, which are
not eco-friendly. The discarded computer materials are called e-waste.
The may contain lead, cadmium etc. SO exposure to harmful
components of e-waste is not good. The mobile phones are also used for
e-ticketing. They are also part of e-waste when discarded.
Recycling of e-waste can reduce the
emission of greenhouse gases.
2. Use of e-ticketing system increases the
use of electronic telecommunication signals in the air. It uses the
telecommunication satellites in space.
3. E-ticketing system uses computer print
out or stationary. Paper comes from wood pulp and hence from
the trees in forests. Thus e-ticketing causes cutting of trees.
The trees have to be regenerated using a disciplined and planned method.
4. I am not sure of these:
The inks used in the printers
or the toners may contain some non eco-friendly substances. They may be
prepared by use of some non eco-friendly processes.
5. These computers along
with all the networking hardware, are always on. The computers dissipate
heat energy continuously.
6. The software has no
effect on the eco-system, as it is present only on the electronic hardware.
It is possible that many parts of computers, except the functioning electronic components, could be made of eco-friendly and recyclable substances. Perhaps there is a need for research on this. Such decisions also depend on the economic feasibility, availability of technology and a big change in the computer industry in the whole world.
Imagine a computer in fine wooden or glass casing!
